SPINDLE-BEARING.

SPECIFICATION forming part of Ietters Patent No. 538,995, dated May '7,`1895.

Application filed July 30, 1894.

.To @ZZ whom it may concern.-

Be it known that I, AURIN VOOD, of Worcester, county of Worcester, Stateof Massachusetts, have invented an Improvement in 5 Spindle-Bearings, ofwhich the following description, in connection with the accompanyingdrawings, isaspeciiication,likeletters and numerals on the drawingsrepresenting like parts. j

This invention has for its object to improve spindle bearings as to'themeans for preserving the proper tit between the' tapered exterior of thepintle of the spindle and the tapered interior of the lateral bearing.To effeet this adjustment the construction of the parts must be such asto enable the distance between the step and that part of the lateralVbearing which surrounds the pintle just above the step to be changed ormade more or less, or, in other words, the lateral bearing and step mustbe separable and be .capable of having their positions changedrelatively one to the other. This can be done by either raising orlowering the lateral bearing, or the step.

In myinvention the adjusting device is located in and accessible fromoutside the oil` ing leg.

Figure l, in vertical section, shows a spindle in a bearing containingmy invention in one practical form; Fig. 2, a top or plan view of theparts shown in Fig. 1, the section of Fig. 1 being in the line Fig. 2.Fig. 3 is a section below the line Fig. 1. Fig. 4c is a' verticalsection showing a modification of my invention; Fig. 5, a section in theline x3, Fig. 4; Fig. 6, an outside View of the bolster. Fig. 7 showsvthe lateral bearing in longitudinal section, and Fig. 8 a section inthe line Fig.

The rail A, on which is the supporting case B, is secured by nut C, andthe sleeve Whirl spindle D having a tapered pintle, are all as usual.The supporting case hasan inclined oiling leg or branch b, through whichis passed the oil to oil the spindle and its hearings composed of alateral bearing @tapered internally, and a step d. I have provided thebearing c externally with a suitable notchior shoulder c', and I haveinserted in the hollow 5o leg or branch an adjusting device e, shown asSerial No. 519,022. (No model.)

" a hollow shaft having a shoulder at 2 to rest against a shoulder ofthe branch, the inner end of said adjusting device having an ec-lcentric projection e to enter the notch c of the bearing c, so that thepartial ,rotation of said adjusting device by a screw-driver or otherproper tool engaging the notch e2 thereof, enables the position of thebearing c to be changed relatively to the step to provide for the properit between the exterior of the pin- 6c tle and the interior of thebearing, a suitable set screwfserving to hold the adjusting device inadjusted position.

In my invention it will be seen that the adjustment provided for may beeffected readily While the spindle is running as Well as while at rest,and Without the loss of oil.

In the modification of my invention Figs.

4 to 8, I have provided for moving the step 'rather than the lateralbearing, one being the 7e equivalent of the other in result, andtherefore an equivalent. Referring to said modiication, the lateralbearing g is prolonged, and its lower end is so fixed with relation tothe outside supporting case that it cannot rise therein when eecting therelative adjustment of the parts to secure the proper tit between theexternally tapered pintle and the tapered interior of the said bearing,the connection being shown as effected by a screw- 8o thread at g2. Thebearing g is grooved externally for part of its length to receive theshank h of the step h', the latter being extended into the bearing andacross the pintle chamber in a slot h2. The shank his notched at h3 tobe engaged by a suitable projection h4 on the adjusting device h5,placed in the oiling leg or branch vm, the rotation of said adjustingdevice with its projection or projections h4 in engagement with theprojectionsV 9o h3 moving the step to the extent desired to make theproper lit between the pintle and lateral bearing.

' In my invention the adjusting device for changing the relativepositions of the lateral bearing and step to insure the proper fit orlooseness between the tapered pintle and step,

is located above the top of the spindle-rail and it is shown asaccessible through the oiling leg, and While I have shown two forms ofroo bined with adjusting mechanism for said bearing and step, located insaid leg orbranch, in positive engagement With one of said members tomove it relatively to the other, whereby the relative position of thesaid lateral bearing and step may be positively changed when desired,for the purposes set forth.

2. The supporting case having an oiling leg or branch, and a lateralbearing and step located in said supportingr case, combined with anadjusting; device located in said leg: or branch, said adjusting devicehaving through it an oil passage and provided at its inner end with aprojection, whereby by the rotation ot' said adj Listing` device therelative positions of the bearing and step may be changed in thesupporting case, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
